Extraction of Honorable Democrats in House of Representatives from CSPAN.org
vote records using Arthur Whitney`s K language

I started doing the analysis in CoSy , but CoSy suffers from the 64k limits of its antique DOS origin .

I have uploaded the files :
art1raw.txt The raw text copied from the CSPAN HTML source for the Article 1 vote .
art1.txt Cleaned up ASCII file , Article 1 .
art3.txt Cleaned up ASCII file , Article 3 .
So you can download them , download K and do your own analyses .

 
  In CoSy/APL :
 Had to do in parts so this is last iteration of reading CSPAN page source .
  
  rho Q is 20000 40000 ASCIIREAD '\COSY\ToCoSy.TXT' |>| 6363  |#|
  rho QW is Q  RPL '<tr><td><b>\ '                |>| 5599  |#|
  rho QW is QW RPL '</b></td><td></td><td> ; '    |>| 4497  |#|
  rho QW is QW RPL '</td><td>   </td><td align=center>  ; ' |>| 2699  |#|
  rho QW is QW RPL '</td></tr> '                  |>| 2177  |#|
  rho QW is QW RPL '<tr></tr><tr></tr>'           |>| 2087  |#|

 K :
 Seeing that this cleaned up the text sufficiently , and to go further in
  CoSy would be a pain , I decided it was a good time to try to do something
  practical in  K .
 These lines can be copied into to a running  K  process to execute .

Note that this code will work with world class efficiency on gigabyte sets of data .

I`ve had a running debate with some core K programmers about the use of Boolean vectors in K versus traditional APLs . I`d ask how else they would handle the logic here . I think the only real difference is that `where ~ `& converting Booleans to Indexes replacing compression : V / iota rho V in APL .
I continue to feel the lack of true Bools in K is a substantial limitation .
